Moringa oleifera Lam. (Family Moringaceae) is well – known for its various medicinal properties. It grows wild in the tropical and subtropical areas of Asia, Africa and the Middle East. In Nigeria, Moringa oleifera trees are planted at a large scale especially in the northern part of the country. It has been widely used in the treatment of certain diseases as a traditional medicinal herb. Antimicrobial activity is the most studied property of Moringa oleifera. Many studies have shown that nearly all types of Moringa oleifera tissues exhibit antimicrobial activity including antibacterial, antifungal, antiviral and anti parasitic property. This review describes progress on research conducted to understand the antimicrobial activity of Moringa oleifera and discusses the potential use of Moringa oleifera in the control of pathogenic microbes. Key words: Antimicrobial activity; Moringa oleifera; pathogenic microbes, control.

Moringa oleifera is a versatile horticulture tree with important medicinal, nutritional and industrial applications, widely distributed and used in India. The Moringa tree originated in India and was introduced to Africa from India and other countries as a health supplement. Almost all parts of the plant have shown nutritional value and are used in India for a variety of food preparations. In India, M. oleifera leaves are available in powder to treat mild malnourishment in children. About all parts like leaves, seeds and pods are used as vegetables. Phytochemicals such as flavonoids, tannins, triterpenoids, saponins, flavonoids, anthraquinones, alkaloids and others, are responsible for the medicinal value of this plant. This species is rich in protein, fatty acids, vitamins and minerals that form part of its quality as superfood. It has been reported to have strong antimicrobial, antioxidant, anti-inflammatory, hepatoprotective, diuretic, anthelminthic and antiurolithiatic properties, among others. People in India use this species to treat common illnesses because of its availability and easy preparation. This review provides information on the significant potential of Moringa and its nutritional, medicinal, pharmaceutical and industrial values.

The seed extracts of Moringa oleifera has been studied as alternative coagulating agent to chemicals commonly used in order to minimize costs while reducing environmental impacts and human health arising from traditional processes of wastewater treatment. This work studied the performance of the aqueous extract of Moringa oleifera seed in the removal of four different types of textile dyes classified as dispersed, acidic, basic and reactive. Studies with aqueous and saline solutions were performed aiming to improve performance in the removal of textile dyes, and stability testing on the storage time of the extract of Moringa oleifera. Studies were performed using spectrophotometric analysis by means of calibration curves of textile dyes in an aqueous medium.The results showed that the seed extract of Moringa oleifera was quite efficient in the removal of textile dyes, except for the cationic type. Regarding the behavior of textile dyes in aqueous solution and the saline extract were not found significant differences in terms of removal. Other promising results were obtained to evaluate coagulant activity of the extract up to three days storage at room temperature. This fact is important from the operational aspect arising from the use of the extract on a large scale: the possibility to prepare a larger amount of extract, without loss of coagulant activity may enable the utilization of this resource

Moringa oleifera presents important medicinal properties, and its seeds are used to treat water for human consumption and wastewater. The aim of the present study was to analyze the initial growth of M. oleifera seedlings in enriched commercial substrate with differing doses of controlled release fertilizer. The experimental was designed in randomized blocks, with four repetitions of 16 seedlings each. The treatment used doses of controlled release fertilizer, with 0; 2; 4; 6; and 8 kg m-3 of commercial substrate. A hundred days after installing the experiment, the following characteristics were analyzed: height of the aerial part; diameter of the root collar; length; volume; and dry mass of the roots and aerial part. Additionally, the relation between the height of the aerial part and the diameter of the root collar and the Dickson quality index (DQI) were determined. The data was submitted to analysis of variance and to the Shapiro-Wilk test to verify the normality and regression. Controlled release fertilizer at a dose of 5.37 kg m-3 of substrate is recommended for M. oleifera seedling production.

The inclusive information is provided in present review on traditional uses, antimicrobial activity and pharmacology of Moringa oleifera Lam. It is commonly known as ‘drumstick tree’. M. oleifera is alternative tonic, astringent, emollient, aphrodisiac etc. Bark of this plant is considered as cooling. Seeds of this plant are considered as aphoradisiac. It has a depressant rather than a stimulant effect on the central nervous system. Many pharmacological investigations have been carried out based on its chemical constituents. Extensive literature survey revealed many pharmacological properties includes antibacterial, antifungal, anticancer, anticonvulsant, antidiabetic, antimutagenic, anticlastogenic, anti-fertility, antiulcer, antioxidant, antiviral and wound healing activities

The widespread use of conducting polymers, especially poly(3,4-ethylene dioxythiophene) (PEDOT), within the space of bioelectronics has enabled improvements, both in terms of electrochemistry and functional versatility, of conventional metallic electrodes. This short review aims to provide an overview of how PEDOT coatings have contributed to functionalizing existing bioelectronics, the challenges which meet conducting polymer coatings from a regulatory and stability point of view and the possibilities to bring PEDOT-based coatings into large-scale clinical applications. Finally, their potential use for enabling new technologies for the field of bioelectronics as biodegradable, stretchable and slow-stimulation materials will be discussed.

: In recent times, Moringa oleifera Lam. has become one of the most sought after therapeutic cure-all plants in tropical and subtropical zones, including Jamaica. Anecdotally, the most popular choice of Moringa consumption locally is in the form of functional herbal beverages such as teas and juices, prepared from the leaves of the plant. However, there is little or no scientific evidence to validate the efficacy and or safety of such beverages. An extensive search of scientific literature published over the last decade (2010-2020) related to the nutritional, medicinal and toxicological profiles of Moringa oleifera was therefore conducted, with special emphasis on literature related to the dried leaves and aqueous leaf extracts thereof. Google Scholar, Science Direct and PubMed databases were the main search tools employed. Articles which referred to varieties of Moringa, other than oleifera were excluded from the searches, as were articles which referred to subject matters outside of nutrition, medicinal properties and toxicity. All peer-reviewed journal articles, and other online articles, which referred to the subject matters of interest were critically read and included in the review. This review is a compilation of evidence-based literature, indicating the outstanding nutritive value, high therapeutic potential and the relatively non-toxic properties of the dried leaves and aqueous leaf extracts of Moringa oleifera. Prospects for their application in the development of safe and efficacious functional herbal beverages are indicated.
